Custom Printed Poly Mailers and Fulfillment Bags for Ecommerce Brands
Your packaging ships with every order. Excellent Poly manufactures custom printed poly mailers and fulfillment bags for U.S. ecommerce brands, apparel companies, subscription businesses, and 3PLs that need branded packaging in bulk — built to your specs, not pulled from a stock catalog.
Most ecommerce brands eventually outgrow generic stock mailers — not because they stop working, but because they stop representing the brand. We work with U.S. brands and fulfillment operations that are ready to make packaging part of the customer experience, not an afterthought.

The Bag Your Customer Receives Is Part of Your Brand Experience
For an ecommerce brand, the unboxing moment is often the only physical interaction a customer has with your product. A plain poly mailer communicates nothing. A custom printed mailer with your logo, colors, and messaging tells customers you paid attention to the whole experience — not just the product inside.
Custom printed poly mailers also serve an operational purpose. The right size, thickness, and closure type reduces packing errors, minimizes returns from transit damage, and makes your fulfillment process more repeatable — whether you run an in-house warehouse or work with a 3PL.
Excellent Poly works with ecommerce brands and fulfillment operations that need custom bags in commercial quantities. We are not the right fit for one-time small runs. We are the right fit when packaging is part of your ongoing shipping process.
Ecommerce & Fulfillment Bag Options
Different fulfillment workflows and shipping applications call for different bag formats. Here are the most common options for ecommerce, DTC, and fulfillment packaging.
Poly Mailer Bags
Poly mailers are the standard for ecommerce shipping of soft goods — lightweight, durable, water-resistant, and fully brandable. One of the most cost-efficient shipping formats for apparel, accessories, and other non-fragile products.
Best for:
- Apparel and clothing brands
- DTC and direct-to-consumer shipping
- Subscription boxes and recurring shipments
- Accessories, soft goods, and textiles
- Any non-fragile product where lightweight shipping matters
Flat Poly Bags
Flat poly bags support inner packaging, product organization, and pre-shipment product protection without the closure hardware of a mailer. Often used inside larger packages or for products bagged before going into a shipping container.
Best for:
- Inner product packaging within a larger shipment
- Apparel protection before boxing
- Parts, accessories, and product kits
- Organized fulfillment workflows
- When additional details need to be printed on the bag
Permanent Tape Closure Bags
Permanent tape closure bags provide a tamper-evident, self-sealing format useful for product packaging, fulfillment inserts, and secure shipping where a reliable closure is needed without additional materials.
Best for:
- Product kits and assembly packaging
- Secure shipping inserts
- Apparel folded and bagged before shipment
- Documents and certificate packaging
- Multi-item fulfillment bags
Die Cut & Patch Handle Bags
Handle bags support retail, pickup, event, or customer handoff applications where branded presentation and carrying convenience matter. Perfect for showing off your brand with every sale.
Best for:
- Retail handoff and boutique packaging
- In-store pickup orders
- Branded merchandise and event bags
- Trade show and promotional distribution
- Lightweight retail product handoff
Ecommerce and Fulfillment Buyers We Manufacture For
Apparel and Clothing Brands
Apparel brands shipping direct-to-consumer represent one of the strongest use cases for custom poly mailers. The right mailer size, gauge, and print design can significantly improve both the unboxing experience and shipping efficiency.
3PLs and Fulfillment Operations
Third-party logistics companies and fulfillment warehouses often manage packaging for multiple client brands. Custom printed bags allow 3PLs to provide branded packaging as a service while standardizing their own packing workflows.
DTC and Subscription Brands
Subscription and direct-to-consumer brands typically have high repeat shipment volume and benefit most from custom packaging — both for brand consistency and for the operational advantage of bags sized and spec’d for the specific product being shipped.
Distributors and Wholesale Shippers
Businesses shipping wholesale orders to retail accounts often need custom bags for organized, professional product packaging that holds up to the handling demands of distribution environments.
Built Around Your Brand and Shipping Workflow
Ecommerce packaging isn’t one-size-fits-all. A mailer for a clothing brand shipping 500 orders a day has different requirements than one for a subscription box company shipping monthly. We build around your specific product, shipment profile, and brand. For ecommerce applications, available options include:
- Custom bag dimensions to match your product size
- Film thicknesses from .001 to .006
- PE, PP, and Coex material options
- White, black, colored, or clear film
- Permanent tape closures
- Lip and tape configurations
- Custom printing on one or both sides
- Logo, brand graphics, messaging, and return address
- Up to 10-color printing
- Production runs starting at 30,000 bags
Best for Brands That Ship Consistently at Volume
Excellent Poly’s minimum order is 30,000 bags. That makes us the right fit for ecommerce brands and fulfillment operations where packaging is a recurring cost of doing business — not a one-time purchase.
If you are early in your business and still testing shipping volume, we may not be the right fit yet. But if you are already shipping consistently and spending money on generic mailers that do nothing for your brand, the economics of custom printing at 30,000 units typically make sense very quickly.
What We Need to Quote Your Ecommerce Packaging

If you have multiple SKUs with different size requirements, let us know — we can often quote multiple sizes in the same order.
Frequently Asked Questions
What is a poly mailer bag?
A poly mailer is a lightweight plastic shipping bag made from polyethylene film, typically with a self-adhesive closure strip. They are water-resistant, puncture-resistant, and used primarily by ecommerce businesses to ship apparel and other soft, non-fragile products. Custom printed poly mailers include brand graphics, logos, and messaging on the exterior of the bag.
Are poly mailers good for shipping clothing?
Yes. Poly mailers are one of the most common shipping formats for apparel, textiles, and accessories. They are lightweight, reducing postage costs, and provide adequate protection for items that do not need rigid packaging. Custom printed versions allow apparel brands to present their brand consistently in the shipping experience.
What is the difference between a poly mailer and a permanent tape closure bag?
A poly mailer is typically used as the outer shipping package, with an adhesive flap that seals the bag for transit. A permanent tape closure bag has a built-in adhesive strip used to seal a bag that may function as inner packaging, product protection, or a secondary bag within a larger shipment. The right format depends on how the bag is used in your fulfillment workflow.
Can you print our logo on poly mailers?
Yes. Excellent Poly specializes in custom printed poly bags. Poly mailers can be printed with logos, brand colors, messaging, return address information, and other graphics up to 10 colors.

The minimum order is 30,000 bags.
How long does production take?
Typical lead time is 2 to 3 weeks from artwork approval and order confirmation.
Are these bags made in the USA?
